2009-03-19[ARM] pass reboot command line to arch_reset()Russell King
OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

2009-03-15[ARM] make page_to_dma() highmem awareNicolas Pitre
If a machine class has a custom __virt_to_bus() implementation then it must provide a __arch_page_to_dma() implementation as well which is _not_ based on page_address() to support highmem. This patch fixes existing __arch_page_to_dma() and provide a default implementation otherwise. The default implementation for highmem is based on __pfn_to_bus() which is defined only when no custom __virt_to_bus() is provided by the machine class. That leaves only ebsa110 and footbridge which cannot support highmem until they provide their own __arch_page_to_dma() implementation. But highmem support on those legacy platforms with limited memory is certainly not a priority. Signed-off-by: Nicolas Pitre <nico@marvell.com>

2009-02-23[ARM] OMAP3: update ES level flags to discriminate between post-ES2 revisionsPaul Walmsley
Some OMAP3 chip behaviors change in ES levels after ES2. Modify the existing omap_chip flags to add options for ES3.0 and ES3.1. Add a new macro, CHIP_GE_OMAP3430ES2, to cover ES levels from ES2 onwards - a common pattern for OMAP3 features. Update all current users of the omap_chip macros to use this new macro.

2009-02-19[ARM] omap: add support for bypassing DPLLsRussell King
This roughly corresponds with OMAP commits: 7d06c48, 3241b19, 88b5d9b, 18a5500, 9c909ac, 5c6497b, 8b1f0bd, 2ac1da8. For both OMAP2 and OMAP3, we note the reference and bypass clocks in the DPLL data structure. Whenever we modify the DPLL rate, we first ensure that both the reference and bypass clocks are enabled. Then, we decide whether to use the reference and DPLL, or the bypass clock if the desired rate is identical to the bypass rate, and program the DPLL appropriately. Finally, we update the clock's parent, and then disable the unused clocks. This keeps the parents correctly balanced, and more importantly ensures that the bypass clock is running whenever we reprogram the DPLL. This is especially important because the procedure for reprogramming the DPLL involves switching to the bypass clock. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-02-14[ARM] omap: arrange for clock recalc methods to return the rateRussell King
linux-omap source commit 33d000c99ee393fe2042f93e8422f94976d276ce introduces a way to "dry run" clock changes before they're committed. However, this involves putting logic to handle this into each and every recalc function, and unfortunately due to the caching, led to some bugs. Solve both of issues by making the recalc methods always return the clock rate for the clock, which the caller decides what to do with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-02-08[ARM] OMAP clock: drop clk_get_usecount()Paul Walmsley

2009-02-08[ARM] omap: create a proper tree of clocksRussell King
Traditionally, we've tracked the parent/child relationships between clk structures by setting the child's parent member to point at the upstream clock. As a result, when decending the tree, we have had to scan all clocks to find the children. Avoid this wasteful scanning by keeping a list of the clock's children.

2009-02-08[ARM] OMAP2 SDRC: add SDRAM timing parameter infrastructurePaul Walmsley
For a given SDRAM clock rate, SDRAM chips require memory controllers to use a specific set of timing minimums and maximums to transfer data reliably. These parameters can be different for different memory chips and can also potentially vary by board. This patch adds the infrastructure for board-*.c files to pass this timing data to the SDRAM controller init function. The timing data is specified in an 'omap_sdrc_params' structure, in terms of SDRC controller register values. An array of these structs, one per SDRC target clock rate, is passed by the board-*.c file to omap2_init_common_hw(). This patch does not define the values for different memory chips, nor does it use the values for anything; those will come in subsequent patches. linux-omap source commit is bc84ecfc795c2d1c5cda8da4127cf972f488a696.

Rename the OMAP2xxx-specific functions to use an 'omap2xxx' prefix rather than an 'omap2' prefix, and use "sdrc" in the function names rather than "memory."

2009-02-08[ARM] OMAP3 clock: avoid invalid FREQSEL values during DPLL rate roundingPaul Walmsley
The DPLL FREQSEL jitter correction bits are set based on a table in the 34xx TRM, Table 4-38, according to the DPLL's internal clock frequency "Fint." Several Fint frequency ranges are missing from this table. Previously, we allowed these Fint frequency ranges to be selected in the rate rounding code, but did not change the FREQSEL bits. Correspondence with the OMAP hardware team indicates that Fint values not in the table should not be used. So, prevent them from being selected during DPLL rate rounding. This removes warnings and also can prevent the chip from locking up. The first pass through the rate rounding code will update the DPLL max and min dividers appropriately, so later rate rounding passes will run faster than the first. Peter de Schrijver <peter.de-schrijver@nokia.com> put up with several test cycles of this patch - thanks Peter. linux-omap source commit is f9c1b82f55b60fc39eaa6e7aa1fbe380c0ffe2e9.

2009-02-08[ARM] OMAP2/3 clockdomains: combine pwrdm, pwrdm_name into union in struct ↵Paul Walmsley
clockdomain struct clockdomain contains a struct powerdomain *pwrdm and const char *pwrdm_name. The pwrdm_name is only used at initialization to look up the appropriate pwrdm pointer. Combining these into a union saves about 100 bytes on 3430SDP. This patch should not cause any change in kernel function. Updated to gracefully handle autodeps that contain invalid powerdomains, per Russell King's review comments.

2009-02-08[ARM] OMAP: Fix sparse, checkpatch warnings in OMAP2/3 PRCM/PM codePaul Walmsley
Fix sparse & checkpatch warnings in OMAP2/3 PRCM & PM code. This mostly consists of: - converting pointer comparisons to integers in form similar to (ptr == 0) to the standard idiom (!ptr) - labeling a few non-static private functions as static - adding prototypes for *_init() functions in the appropriate header files, and getting rid of the corresponding open-coded extern prototypes in other C files - renaming the variable 'sclk' in mach-omap2/clock.c:omap2_get_apll_clkin to avoid shadowing an earlier declaration Clean up checkpatch issues. This mostly involves: - converting some asm/ includes to linux/ includes - cleaning up some whitespace - getting rid of braces for conditionals with single following statements Also take care of a few odds and ends, including: - getting rid of unlikely() and likely() - none of this code is particularly fast-path code, so the performance impact seems slim; and some of those likely() and unlikely() indicators are probably not as accurate as the ARM's branch predictor - removing some superfluous casts linux-omap source commit is 347df59f5d20fdf905afbc26b1328b0e28a8a01b.

Add non-CORE DPLL rate set code and M,N programming for OMAP3. Connect it to OMAP34xx DPLLs 1, 2, 4, 5 via the clock framework. You may see some warnings on rate sets from the freqsel code. The table that TI presented in the 3430 TRM Rev F does not cover Fint < 750000, which definitely occurs in practice. However, the lack of this freqsel case does not appear to impair the DPLL rate change. linux-omap source commit is 689fe67c6d1ad8f52f7f7b139a3274b79bf3e784.
